METHOD OF APPLYING COATING AND COATED METAL ARTICLE Russian patent published in 2012 - IPC C23C14/28 B23K26/06

Abstract RU 2467092 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to application of coatings of metal article with large surface areas. In compliance with this method, coating is applied by VHF-laser pulses in scanning target surface by laser beam. Note here that laser pulse repetition rate is selected to make, at least, 1 MHz. Scanning is carried out at the rate of over 10 m/s by means of rotary optical scanner including, at least, one laser beam reflection mirror.

EFFECT: higher efficiency, better quality.
